BICYCLE.

srEcIFioA'rIoN forming part of Letters Patent No. 613,943, dated November 8, 1898. Application filed May 29, 1896. Serial No. 593,641. (No model.)

To all whom it may concern:

Be it known that I, THEOBALD E. J. SCHAI- BLY, a citizen of the United States, residing at New York, (Brooklyn) in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Bicycles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part 0 this specification.

Figure l is a side elevation of a bicycle embodying my improvements. Fig. 2 is a front elevation. Fig. 3 is a side view of a modification. Fig. 4 is a front view of the same. Fig. 5 is a cross-section on the line new of Fig. 4:. Fig. 6 shows two sections at right angles to each other of the ratchet mechanism in Figs. 3, 4, and 5. Figs. 7, 8, 9, and 10 are views of another modification.

In the drawings I have shown a bicycle whose general features of construction are more or less similar to those of the machines now in use. A indicates the rear wheel, B, the front wheel, and the intervening main frame is represented, more or less conventionally, by O D E F, there'being the usual vertical strut-standard G. At the front end of this frame, which is of the diamond type,

there is the usual tubular bearing at H, in

which is fitted the rotary upright rod or standard I, connected to the forks I of the front wheel. At J there is mounted the sprocketwheel on the short shaft, having the pedals and cranks L for driving by foot-power, this sprocket being connected with the sprocket wheel K on the rear wheel by the chain M.

As above stated, the parts which have been referred to may be of the usual kind, or, if preferred, of any desired sort.

One of the principal objects of this invention is to provide bicycles of this general class with supplemental power devices of an improved sort, whereby the hands of the rider can be utilized either separately or conjointly with the foot-power devices for propelling the machine.

0 indicates a bracket secured to and movable with the standard I and forks I of the front-wheel frame, it preferably having an eye 0 surroundingthe standard I below the tubular bearing H, vertical .bars 0 o, and a clamping-eye 0 which surrounds the standard I above the bearing H. In this bracket there is mounted a shaft P, having at its ends cranks p p. On this crank-shaft P there is a relatively large sprocket-wheel Q, vwhich, by means of a chain q, is connected with a sprocket-wheel R on the axle of. the front wheel B.

The shaft P is rotated by means of avibratable segmental sprocket-wheel T. The latter is secured to a shaft T, which is mounted in the front-wheel standard I, or in a suitable bearing secured thereto.

tis a chain which engages with the teeth of the segmental wheel T. The ends of this chain are connected to rods or pitmen U U, which in turn are pivoted to the cranks p of the shaft P.

S S are the handle-bars provided with the handles 8' s. T of the segmental wheel T. 1

It will be seen that the rider when in his seat can impart vibrations which are vertical or nearly vertical to the handles and handle -bars. These will in turn vibrate the segmental wheel T, and the latter, through the chain 25 and the links U,- willcause the shaft P to rotate. This, through the sprocketwheel Q, chain q, and wheel R, imparts rotation to the wheel B.

In Figs. 3,4, and 5 I have shown a modification of the devices which transmit the power from the segmental sprocket-wheel T to the shaft P. In this case thecranks p are dispensed with and a ratchet-wheel W is employed, the ratchet devices being connected with the chain t by leather straps VV. The ratchet mechanism may be of any suitable form, that whichI prefer being shown in the drawings.

In Figs. 7, 8 9, and 10 there is shown another way of carrying out my invention. In this case the sprocket-segment T and the chain 6 are dispensed with and in their place are employed three bevel-wheels U uu. The bevel-wheel U is connected to the handlebars and can be vibrated with them. The wheels u u are mounted loosely upon a vertical shaft U which is mounted in an extension U of the bracket. The lower endof These are secured to the shaft 7 shaft U carries a bevel-wheel u, which meshes with a bevel u on the shaft P. This shaft and its sprocketconnecting devices joining it to the ground-wheel are the same as above described. The wheels u u can be connected to the shaft U by means of ratchet mechanisms at 10 10 \Vhen the handle-bars and the wheel U are rocked in one direction, the wheel u is connected with the shaft and proper rotation is imparted to the shaft U and when wheel U is rocked in the opposite direction the wheel it turns loosely on shaft U and the wheel 1!, is connected with the shaft by its ratchet at 10 Consequently the driven parts can be actuated continuously in one direction.

With a mechanism of either of the sorts herein it will be seen that the rider is enabled to propel the wheel by the hand devices independently of those for driving the wheel Aand that the two sets of driving means can be used separately or conjointly, as desired.

I am aware that it has been heretofore proposed to apply power to the front wheel of a bicycle from the handle bars by connecting said handle-bars with the upper ends of connectingrods the lower ends of which were connected with cranks on the axle of the bicycle wheel or on a shaft connected by sprocket-gearing with the axle; also, that it has been proposed to connect rods attached 'to pivoted handle-bars of a velocipede with bell-crank levers which were also connected by rods with clutch devices adapted to engage with the pedal-shaft of the machine. My improvements, however, are to be clearly distinguished from such constructions as those referred to. In both of the last said constructions the handle bars for actuating the hand propelling devices were necessarily vibrated when the machine was being propelled by the pedals, whereas, as will be seen from an examination of the drawings, particularly of Figs. 3 to 9, with my construction the handle-bars will remain stationary when the bicycle is being propelled from the pedals L and can be used in the ordinary manner for guiding and directing the movements of the front wheel. Again, by connecting the handle-bars with the front-wheelpropelling devices in the manner herein shown and described it will be seen that I avoid entirely the use of relatively-long connecting-rods, which have been heretofore employed, and also that the hand propelling devices are entirely independent of and separated from the pedal mechanism provided for driving the bicycle by acting on the rear wheel in the ordinary manner. By my construction all of the hand propelling mechanism is supported on the rotary steerin g-frame, in which the front wheel is mounted, and can therefore be readily applied to any ordinary form of bicycle, whereas in constructions in which a common driving-shaft is adapted to be actuated either by pedals or from the handlebars by which the machine is guided a machine must be specially constructed to permit of the necessary arrangement of parts adjacent to said driving-shaft.

I am aware that my improvements are adapted to be applied not only to bicycles of the form herein illustrated, but also to other forms of such vehicles, to tricycles, &c.

What I claim is- 1. The combination with the rear wheel, the main frame, and the front-wheel frame having a standard mounted loosely in the main frame, of the power-transmitting devices connected with the front ground-wheel, the driving devices, the handle-bars connected to the driving devices,and the bracket for the powertransmitting devices, said bracket being connected to the front-wheel standard below its bearing on the main frame, and also above said bearing, substantially as described.

2. The combination of the rear wheel, the front wheel, the intervening main frame, the frame for guiding and supporting the front wheel, the sprocket mounted on a bracket carried by said front-wheel frame, and geared to a shaft, U a sprocket-chain connecting said sprocket with the front wheel, a bevel-gear, u, loosely surrounding the shaft U a ratchet mechanism for connecting said gear with said shaft when rotating in one direction, another bevel-gear u, loosely surrounding the said shaft, U a ratchet mechanism for connecting said gear u, to said shaft when rotating in a direction opposite to that in which the gear 11/ moves when connected to said shaft, and handlebars arranged to vibrate about a central point and connected at their point of vibration with a bevel-gear meshing with both of the aforesaid gears, u, u, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
